About ' * ' not recognized

[naoki ueda]

When I tried to execute the attached file mycalc.c with a command line
argument, it could not be executed normally only in the case of '*'.
'+', '-' and '/' can be executed normally, but the compiler cannot
execute '*' normally. Isn't this a gcc bug?


~/Clearning$ ./mycalc 20 * 30
用法:mycalc 数値1 演算子 数値2
